This bachelor thesis deals with the issue of autonomous collision avoidance of unmanned aerial vehicles (UAVs) in a decentralized environment without a superior coordinating authority. With regard to the growing traffic density and current legislative requirements for determinism and safety (e.g., EASA EPAS 2025), a new part of an algorithm based on the principles of non-cooperative game theory and myopic decision-making is proposed. The main contribution of the thesis is the design, derivation, and mathematical analysis of a payoff function, which in real time balances the effort of the autonomous agent to reach the target with the necessity to maintain safe separation from other traffic participants. The presented non-linear model effectively eliminates the shortcomings of existing approaches, such as numerical instability or undesirable distancing from the target destination (the so-called runaway effect). Mathematical analysis proves the existence of an optimum and the boundedness of the gradient of the proposed function, which improves the properties of the numerical solution. The functionality, robustness, and ability of the algorithm to solve multiple conflicts are subsequently verified through a custom simulation environment in the Python language.
